[0002] Coalbed methane, commonly known as "gas", refers to hydrocarbon gas stored in coal seams, mainly composed of methane, mainly adsorbed on the surface of coal matrix particles, partially free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal and belongs to unconventional natural gas. When the concentration in the coalbed methane mining environment is greater than a certain value, it is easy to cause an explosion and bring safety accidents. Therefore, it is necessary to monitor coalbed methane through relevant monitoring devices.

[0003] In this regard, Chinese Patent Application No.: CN219993690U discloses a coalbed methane monitoring device. It solves the problem that when pumping in coalbed methane, the device ventilates with the outside, and the filter screen can block the dust outside the device, but the filter screen is not easy to install and disassemble. It includes a monitoring device body with an accommodation space inside. An air inlet hole is opened at the top of the inner side wall of the monitoring device body. A detachable dust-proof net is arranged outside the air inlet hole, and an installation box is arranged inside the air inlet hole.
